IMPROVEMENT IN SCALES.

Specification forming part of Letters Patent No. 155,753, dated O t -I 17 pp cat o l May 29, 1874.

To all whom it may concern Be it known that we, FREDERICK A. Rrnnmi. andTINIUs OLsEN, both of the city and county of Philadelphia and the Stateof Pennsylvania, have invented a new and useful Improvement in Scales;and we do hereby declare the following to be a clear and exactdescription of the nature thereof, suiflcient to enable others skilledin the art to which our invention appertains to fully understand, make,and use the same, reference being had to the accompanying drawings,making part of this specification, in which Figure 1 is a top view ofone part of our invention. Fig. 2 is an end view thereof. Fig. 3 is atop view of another part of the invention. Fig. 4 is a central verticalsection thereof. Fig. 5 is an end view thereof. Fig. 6 is a top view ofanother part of the invention. Fig. 7 is a transverse vertical sectionthereof in line a: a' of Fig. 6.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in means for lockin g the poise on theweighing-beam. It further consists in a horizontal arrangement of beams,whereby different substances or commodities can be readily andaccurately weighed, without any adjustment or alteration of theapparatus, and without any knowledge on the part of the attendant, andability to tamper with the adjustable parts.

' Referring to the drawings, A represents the platform, which may be ofwell-known form and construction, and connected to the weighingapparatus, as usual. B represents a metal frame, which may be made ofone or more pieces, and is arranged on the mason-work surrounding theplatform A. Flanges C depend from the inner edges of the frame B, andbear against the adjacent portions of the mason-work on which the frameis supported. The inner sides D of the flanges are beveled or sloped,the narrowest part being below, so that the space D between the sides Dand the platform A widens downwardly. The upper faces of two oppositesides of the frame B are constructed with guards G, which are of flaringform, and extend transversely 011 the said two sides of the frame.

It will be seen that the top of the platform A and metal frame B are ofuniform height or level, whereby wheels of vehicles are permitted topass over the edges of the platform without striking against thesame,,whereby jarring of the platform is prevented, and the fulcru ms ofthe levers are relieved.

Should stones, dirt, or other substances fall in between the frame andplatform, lodgment thereof is prevented by the sloping sides of theflanges of the frame, causing the descent of the said substances. Theflanges G serve to hold the frame in position on the masonwork.

H represents a series of weighing-beams, which are arranged horizontallyside by side, and mounted on a chair, J, located in a box or casing, K,which is under look and key, or otherwise reliably secured. At thecenter of the series of the levers is the main beam L, which is arrangedparallel with said series, and a portion of said beam extendstransversely, at a, over the series of beams H above the fulcrumsthereof, then passes longitud inally, at b, at the sides of the seriesof said beams to near the forward ends thereof, where it extends underthe same, at 0, so that the rear portion a is above the beams H, and thefront portion 0 beneath the same. Beneath the forward ends of the beamsH are arranged pawls or latches M, which are hinged to the case K, andproject through openings N therein, so as to be conveniently reached andoper ated. Each opening or slot N has a lateral extension, d, at itsupper end, for the reception and support of the relative pawl or latch Mwhen the latter is placed therein.

It will be seen that, as the front portion 0 of the beam L bears againstthe under side of the beams H, the weighing action of the platform. ofthe scale, which is connected to the main beam, will cause the beams Hto move with the main beam.

When, however, the beams H are elevated at their forward ends, theyclear the portion 0 of the beam L; consequently said beams H arerendered inoperative.

The series of beams H are auxiliary to the main beam, but each beam Hhas a motion independent of the other, and is designed for weighing adifferent commodity or substance, or for what is generally known ascharging.

The poises of the beams will be set to a desired amount, and then thecase K is locked, or otherwise secured.

Vhenever a beam, H, is not required at a given time, it is disconnectedby lifting its relative latch or pawl, and holding the latter in theextension part (I of the notch in which it moves.

Suppose it is desired to weigh five hundredpounds of iron. Then all ofthe beams, excepting the one for iron previously set at five hundredpounds, are elevated, and thus disconnected from the main beam. Thevehicle with the iron is then run on the platform of the scale, and, ifthe right amount is on hand, the main beam L, having its front portion 0bearing against the beam for weighing iron, acts with said beam, andindicates the result, for which purpose a finger, P, may be secured tothe forward end of the main beam, and project beyond the casing K, whereit operates with the index It.

If one hundred pounds of lime are to be weighed, we elevate ordisconnect all of the beams excepting the one designed for limepreviously set at one hundred pounds, and the operation is the same asbefore.

The disconnection of the beams H is accomplished by raising the pawls orlatches M, which operation elevates the beams H, and causes them to beclear of the main beam L. By lowering the pawls or latches, the beams Hare again operative with the main beam.

The poise S embraces and slides on the weighing-beam and in order tolock the two parts, we form in one side of the poise an opening, and inthe same fit a wedging-pin,

T, which is adapted to engage either with the notches or teeth of thebeam or openings formed therein, in such position that the pin willdrop, or may be moved thereinto.

If the pin engages with the notches or teeth of the beam, the part ofthe former that comes in contact with said teeth or notches should betoothed to properly engage therewith.

WVhen the poise is to be adjusted, the W6C gin g-pin T is withdrawn, andthe poise shifted. \Vhen the proper spot is reached, the pin ispermitted to drop, or returned to its first position, and thus thelocking of the beam and poise is accomplished by the wedging of the pinand beam.

We are aware that Letters Patent have been granted for charging scales,for the purpose of weighing different substances or commodities withoutalteration of the apparatus, or knowledge on the part of the attendant,and therefore disclaim such features; but

Having thus described our invention, what we do claim as new, and desireto secure by Letters Patent, is-

l. The combination, with the sliding poise S and beam, of the slidingwedge-pin T, for locking said poise and beam, substantially as shown anddescribed.

2. The series of l1orizontally-arranged auxiliary beams H, and the mainbeam L, with transverse extension engaging with said beams H,substantially as in the manner and for the purpose set forth.
